Avenue Theme - Looking to change blog post landing page layout

I’m using the Avenue theme.

Currently my blogs populate in a column format; each entry stacked on the previous one (first screenshot).

I am hoping to find a simple solution (CSS, liquid code change is fine) for them to populate in rows of 3 across (grid format) (second screenshot).

Help!? TIA!

Hi, please try this code

@media screen and (min-width: 1080px) {
    #shopify-section-blog-template .container:nth-of-type(3) {
        display: flex;
        flex-wrap: wrap;
    }
    #shopify-section-blog-template .container:nth-of-type(3) > div:not(:last-child) {
        width: 33%;
    }
}

Where does that get inserted at?

Thank you for the reply!!

You need to add this code at the end of file theme.scss that is stored inside yout Theme assets folder.

Remember to do a backup of the theme first by following the guide Duplicating themes

THANK YOU SO MUCH!
